That may be the case for the application. However, depending on the
installation, shared libraries may be overwritten when a new
installation is carried out and cause older software versions to stop
working.

The Windows version of Qgis allows you to run multiple versions on
your computer side by side. I personally haven't used the Windows
version for several years so I can't be sure if you will have any
issues running 3.0 alongside your current version. I run many of the
editions I have in virtual machines. If your PC has 8 GB or more of
memory, or if you have access to another computer that can run Linux,
then you can try it out in a Linux virtual machine or physical
computer environment without disturbing your current installation.

hello Patrick, thanks for your ideas. I will try the no plugins
option.
The program will run with no project loaded and it will run older
project files but has problems with newer ones for the same project.
I can load an older project file and then add newer layers to it
and reconfigure them, Etc. This is very tedious but will amount to
a recovery. It is better than starting from scratch for sure. But
will the same problem reoccur?
I have contemplated migrating to version 3 but I'm always leery of
upgrades of anything as they often bring problems with them. In
this list I notice many references to installation issues and
things not running. 2.10 is a devil I know.
can I expect any difficulties installing 3.0 +?

Thre are a number of troubleshooting steps to try out
1. Start up qgis using the -noplugins switch or remove all
installed plugins or test removing one at a time.
2. Backup the config file and start with a new empty config.
Qgis 2.10 is well out of support, is there any reason you can't
migrate to 3.0?

hello Phil,
I did open the project file in Word, 2033 pages, and found 13
instances referring to the dxf file. Hard to say if anything
was wrong there, nothing obvious. At least to me. Some other
research I did indicates that maybe there is an authentication
problem, not sure just what that boils down to.
I don't think the dxf file is the problem. I renamed it and
bypassed it on the startup routine which the program accepted
but it still seized up with a spinning cursor. Some things
still function, such as modifying the properties of a layer ,
Etc. But the screen is blank and nothing can be saved.
For some time I have noticed that loading a project file bogs
down for a while and then would resume to completion. Now it
bogs down and blows up. The key message seems to be unknown
exception.
Some older project files do load successfully however...

Can you open a copy of the previous project file in something
like notepad and see if anything obvious can be fixed and or
removed in relation to the DXF layer?

Hello All,
Bad News. I am unable to load a project that normally works
with no problems:
1. QGIS 2.10.1, Windows 7.
2. Project starts to load, loads many layers . . .
3. halts loading "point Entity", a DXF file
4. the DXF file was renamed to trigger the Handle Bad Layers
service
5. this was bypassed but project loading still fails to
complete, cursor spinner on constantly
6. exiting with Save triggers "Unknown Exception"
7. the project file is trashed to 0kb
8. Exiting without Save is OK but no project can be loaded
9. Restoring previous project file versions yields the same
results
10. Loading some other projects works but may have cursor spinner
Any ideas what is going on here? I have rebooted the computer.
Thanks very much . . . .
Cheers . . . . . Springfield Harrison
